Struct futures::sync::oneshot::Receiver [−][src]
A future representing the completion of a computation happening elsewhere in memory.
This is created by the oneshot::channel
function.
Implementations
impl<T> Receiver<T>
[src][−]
pub fn close(&mut self)
[src][−]
Gracefully close this receiver, preventing sending any future messages.
Any send
operation which happens after this method returns is
guaranteed to fail. Once this method is called the normal poll
method
can be used to determine whether a message was actually sent or not. If
Canceled
is returned from poll
then no message was sent.
pub fn try_recv(&mut self) -> Result<Option<T>, Canceled>
[src][−]
Attempts to receive a message outside of the context of a task.
Useful when a Context
is not available such as within a
Drop
impl.
Does not schedule a task wakeup or have any other side effects.
A return value of None
must be considered immediately stale (out of
date) unless ::close
has been called first.
Returns an error if the sender was dropped.
